Manufacturing Quality Control of 2,2-Dipropylmalonic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies active compound by neutralizing acidic protons with standardized sodium hydroxide solution. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic impurities by weighing residue after high-temperature ashing. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) using plasma-induced atomic emission spectroscopy. |
| Chloride Impurity | Ion Chromatography (IC) | Separates and quantifies chloride ions based on anion exchange retention and conductivity detection. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV absorbance. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled lighting conditions. |
| Solubility in Common Solvents | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., ethanol, acetone) per compendial guidelines. |
| Acid Value | Acid-Base Titration with KOH | Measures free carboxylic acid content by titration with standardized potassium hydroxide in alcoholic medium. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Determines volatile content by measuring mass loss upon controlled heating under inert atmosphere. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization. |
